Answer: \(6(-3m)4=-72m\)


Step-by-step explanation:

Given expression: \(6(-3m)4\)

which is equivalent to \(6\times4(-3m)..........\text{[commutative property of multiplication]}\)

which is equivalent to \(24(-3m)..........\text{[as}6\times4=24]\)

which is equivalent to \(24\times-3m\)

which is equivalent to \(-72m..........\text{[as}24\times3=72]\)
